No, my daughter bought me a new LG phone last year from a reputable dealer which worked fine for a couple of weeks, then when I needed to use my keyboard, the screen went black every time....terribly frustrating when you are talking to someone on the phone and you have to enter a phone number or details about anything and are simply unable to do it.. After enquiring everywhere virtually, because nobody seemed to have any answers, I discovered it is a common occurrence in phones that are either refurbished / rebuilt and then sold as new or is a cheaper version of the real thing and is built entirely in China. Nokia, LG and many of the iPhones available to be bought cheap on Ebay from dealers fall into this category. Generally, wherever you bought your phone from may not do anything for you unless it is still under warranty, and even then it is up to them whether they will cover your screen. My daughter took mine back and they dithered for months, until the warranty expired and we never heard back from them.. It wasn`t something we could claim for on insurance so we lost our money... but that is my story.. If your phone is still able to be taken back to where you bought it, and they offered you another phone, I would take it but keep your options open. Hope this helps !

At the start screeb after the `NOKIA` logo and two wheels there`s a sad smiley :-( and the phone remains in that state. I cant even turn it off using power button. I have to manually remove the battery every time I want to shut it down (frustrated!!) After trying soft reset for a few days, I decided to hard reset the phone. But I cant even perform hard reset. From some post I came to know - I need to press my volume down, power & camera button simultaneously, and when the phone restarts press the volume down & camera button only. Tried several times. But in vain. I additionally tried resetting the phone with microsoft suggested way of turning off the phone (in my case removing battery and putting it back) then turn on, hold the volume down but exclamation mark does not come for my case, it keeps on restarting with NOKIA logo only, still I tried Volume Up, Volume Down, Power, Volume Down (as suggested by microsoft) but no use.

The screen gets turned off during a phone call when the proximity sensor is covered. This is done to avoid accidental touch screen actions when you are in a call.

If the screen gets turned off immediately when dialing a number or receiving a call, check that your phone does not have any object which may cause detection. There are various non-Nokia original screen protectors sold in the market which cover the proximity sensor causing blank screen issues during calls.

You can take the following steps to check the issue. If the screen keeps turned off, the protector may not be of the right size and will block the sensor on the upper part of the front side. Then either remove the protector or cut off the plastic from the blocking area.

1.Make or receive a call with the phone. 2.Once the phone is in a call place your hand 1cm above the screen and display will turn off.

3.Remove your hand and display shall turn back on.

4.Repeat the test steps 1,2,3 for 3 times to verify the proximity sensor function.

You guys know nothing about LCD screens basicaly there are crystals inside of the screen (liquid) if the glass splits then the liquid inside comes out in the main screen. Once this happens the liquid corrupts and the display breaks because of the liquid deflecting the light so basicaly this is only being fixed by a FULL screen reapair about £80.

Its a sensor and its normal. samsung galaxy phones and iphones also do that. its for you not to be able to press anything on the touchscreen while on a call e.g accidentally dropping or hanging up, muting, etc.
